Choosing the right kind of parts to assemble something is the most
important and complicated job to do and it gets even more tiring &
effort-consuming when firearms are concerned. While there are many things to
pay attention to as you assemble your weapon, getting a perfect recoil system
still remains the trickiest part. Buffer tubes are one of the major parts of a
gun/rifle’s recoil system helping in decreasing the shockwave generated by the
What is a Buffer Tube Kit?
while you can buy Buffer Tube kits in the market easily, first you must
know all about the content of the kits. The Buffer tube kit majorly includes 5
parts (depending on fixed or detachable stock)- receiver extension (buffer
tube), buffer, buffer spring, endplate and a castle nut. All the parts are
absolutely necessary to assemble a smooth functioning recoil system. Now, the
variations start with the length of buffer tube and spring along with buffer
material and weight- all of which should be properly aligned in order to get a
Rifle Length Buffer Tubes & Buffers:
The rifle length buffer tube, also called A2 buffer tubeor the extra-long
buffer tube, is generally installed in fixed stock AR rifles and does not
require an endplate. The endplate is used to keep all the assembled buffer tube
components intact but in a rifled tube, those components are supported by the stock
itself. Rifle buffer tubes are plain and basic in design and require long rifle
buffers so that there is no gap remaining in the tube. The A2 buffer tube can
not function with a smaller length buffer- carabine buffer, and that is why
knowing the length of your buffer tube matters.
Carabine Buffer Tubes:
Generally used in collapsible stock pistols, carabine tubes function with
carabine buffers- smaller size and available in varied weights. The weight of
your buffer can be chosen depending on the gas function of the pistol/rifle- a longer
length gas system requires heavier buffers. Carabine buffer tubes measure less
than 16 inches and are manufactured in military specified (mil-spec) and
commercial variations. Many options are available when you buy Pistol buffer
tubes & buffers, unlike rifles buffers.
Right Length = Perfect Reload & Recoil With No Gaps
So, the conclusion is simply- the length of your buffer tube is directly
proportionate to the rifle/ pistol type and same goes for the buffer. Choosing
a wrong length or weight causes the gas and recoil system to collapse and it
either jams the firearm or results in a very high-pressure recoil – damaging
the rifle and the shooter.
